'Unfruitful' in the Bible

Then the men of the city said to Elisha, “Even though our lord can see that the city’s location is good, the water is bad and the land unfruitful.”

“Then [Zion], you will say in your heart,‘Who has borne me these children,Since I have been bereaved of my childrenAnd am barren, an exile and a wanderer?And who has reared these?Indeed, I was left alone;From where then did these children come?’”

“Behold, the days are coming,” says the Lord,“When the plowman shall overtake the one who gathers the harvest,And the one who treads the grapes [shall overtake] him who sows the seed [for the harvest continues until planting time];When the mountains will drip sweet wineAnd all the hills shall melt [that is, everything that was once barren will overflow with streams of blessing].

I will rebuke the devourer for you; it will not destroy the fruit of your soil; your vine in the field will not be unfruitful," says Yahweh of hosts.
